4 Claims.

'I'his invention relates to beds, and has been illustrated as embodied' in expansible beds of the studio couch type.V Although 'some of the features of this invention may be usedv without theV others, the embodiments whichhave been chosen for illustration and description show various of the novel features in combination. In these embodiments the beds comprise two separable por,-V tionsl which are normally secured together by I0 equalizer bars. These equalizer bars have the dual function of maintaining the parts in parallel relationship and of making the movable part run truewith respect to the stationary part.

Among the numerous objects accomplished by this invention, is the provision of a couch which may be economically constructed and which though expansible will have the appearance of the ordinary couch; and the provision of an expansible bed which may be either expanded or entirely separated with the utmost ease alsoY the provision. ofi' ganexpansible. bed structure in which the spring fabrics are only slightly separated vertically without loss of strength as compared with ordinary expansible beds. Y

the invention may consist of certain novel features of construction and operatio-n, as vwill be more fully described and particularly pointed out in the specification, drawings and claims appended hereto. 5

Figure 12 is a fragmentary perspective view of a slight modification of the structure of Figures 9 to 11.

Although my invention may take various forms, only two,with a slight modification have been chosen for illustration, the preferred form being shown vin Figures 1 toVV 8. Each form in its normal or contracted position includes the cushion or mattress 2 supported on a suitableA bed spring and :framev which is preferably hidden vfrom view by the upholstery 4.' Underneath the cushion'2 is,V

a second mattress I5l which is supported directly on the spring fabric 8, which latteris carried by the main frame I inthe usual manner,Vv exceptV for features to be described, VArranged under the: spring fabric 8 is the trundle frame I2 which is'.` provided with the spring fabric I4, and is mountedon the trundle box `I 6. The trundle box is'supported by rollers I8 to permit its free movement from its contracted position to its extended posi- OH; Y

, In the preferred formshown in Figuresrl to 8, the main frame IG is provided with a side bar 2 IJ along its back side, as shown best in Figures 5 and 7. In order to insure the uniform and easy movement of the trundle box I6 and the trundle frame I2, equalizer bars 22 are provided, as best shown in Figure 5. These two bars are. pivoted to each other by a pivot `23. One of themV is pivoted at one end by the pivot 24 to the side bar 2li, vwhile the other one ,is pivoted at lits corresponding end by the pivot 25, to a coupler bar 26` normallyrsecured to trundle frame I2. Eachof the bars is pivoted at its opposite end by thesliding pins 2l, each of'which'slides in a slot 28,l one of which is formed in theside bar 20A and the otherof which is formed in coupler bar 26. To permit the two balance rods 22 to completely collapse under the side bar 2li, one of them may be l Aprovided With a stirrup portion 29 to lit around This stirrup portion is desirable;

the other one. because of the fact that, as shown in Figures 5V and 7, the righthand end ofvone'bar 22 is pivoted to coupler bar 26 below it, and the other end ,of the same bar is pivoted to side bar 20 abovefit. The other bar is just the reverse, so it isv clear thatit is necessary for them to cross one another verticallyrinrsome manner.V With this construction it is clear that the trundle frame must remainparallel relationship with the main frame, so. that; it is impossible-for it to become twisted and move irregularly. The equalizer kbars also'cause the trundle bed to run true, i. e., laterally centered as well as parallel, so that it cannot rub against the main section.

As the trundle box and frame are drawn out, the outward movement is normally limitedby the coupler bar 26, as shown best in Figure 5,'Wherev it is seen that the'en`ds`30 of the barr 26contact Forethis purpose, of course', a drawer could be provided to be drawn out furthen'but under some conditions there would not be room for this further extension. t is therefore preferred that the spring frame be hinged.

The hinging of the spring frame is' shown best in Figure 4, in which it is seen that the frame I2 Y is pivoted to stub legs 32 by suitable pivots 34.

As shown in dotted lines, this pivotal point is located suiiiciently far forward when the legs are fully extended but not separated, to prevent inv lsuspended by the means discussed. The tongues terferenceV with the main bed portion or its 'matsystem of levers and springs best shown in Figure 4 is provided, preferably at each end of the trundle box. Pivotedby pivot 35 near the front side of the trundlebox is a toggle leverv `36 to which by means of pin 3l is pivoted the toggle lever 38 which at itsvother -end is pivoted to the hinged frame I2..by the pivot 39. spring 43 is attached to the trundle box at the pivot 39-and to the end of lever 36 at the point 45 beyond the pivot 31, as shown. As clearly seen from a comparison of Figures 4 and 6, the spring 43 .is drawn out by the lowering of the hinged frame I2. Also, theeffect Vo fzthespring is much stronger relatively When the frame is up than whenit is down,'due to Vtwo causes: rst, the frame in its upper nearly'vertical position `is moreV nearly balanced in itself than when extending horizontally; and second, the levers 36 and 38Vare more nearlyin a straight line, so that a force Y exerted on them'by the hingedfrarne I2 has a smaller component in' the spring expanding direction. Through the 'combination of these'variable features,A and through theiuse of a properv spring, the frame I2 may be made to stayin either position, and at the same timeY be nearly 'enough'balanced in'all positions so that its oper-v ation willv not be diiiicult.Y Also through this combination of variable features, and due tothe fact that the springis in its most eiective posi'- tion with respect to the levers when the frame is about halfway up, there is a tendency for the spring frame I2 to raiseV itself a's-soon as it has been well started. The downward movement of the hinged frame I2 is limited by the shoulders 48 of legs 49 secured to said frame, and arranged to rest on the bracket 56 forming a continuation i Y, of lever-36.,

bar 26 Yis a spring latch 64 punched toxengg` of brackets 56. .The coupler bar26 can bere-fV Y notches 58 when bar 26'is raised onto the tongues leased from the tongues simplyby pressing onfY handles 66 of latches 6,4.- When thus released bar 26Y willdrop into pocket 68 of end bar 10,

where it will remain in a convenient position for Y subsequent attachment. When the trundle box and frame are in their normal position it is desirable thatthey be movable with the main bed frame, and so yconnected therewith that when the main frame is lifted it' Will lift the trundle box Vand frame also.V This result may be very readily secured by providing a hole 14 in each of the front 15 are preferablynotched as shown to lock the Vbed in its contracted position duringinoving. Y, The rear sideY` of the trundle section Will-be supends of `the bed are covered withV upholstered4 Y panels while the main section of the bed is-pro- Vvided with a. cover secured thereto by .nailing strips in Vclose proximityto said panels. The mattresses may be of any type,` or may be of diierent types,"and'that on the -main section may be conveniently built onto the frame. Of course,.ii itshould be desiredto revise the couch so that the uppersection slidesA 01T of the lower section, the .upholstery and ,other details wouldV ,be1 changed accordingly.V Y j i From the foregoing;` and from the'drawings, it may befseenthat .this bed in its normal con-v dition maybe used as any other bed of thedrawup type,A the trundle section being hidden from drawn out with the utmost easeV due toV the particular use of the equalizer bars, as'shown.` The coupler bar 26 acts as a stop forthe trundlesection When-.this section reaches the proper position for coacting with the'main section to form one doublev bed. 'However', if it is desired to use the two sections as twin beds, it is merelynec essary to press the handles 66 of the spring latches 64V and allow the couplerbar- 26 to drop off of the bracket '56. The trundle section is then entirely disconnected from the main section, and may be moved around at will. When it is` desiredV to reconnect the beds, itis merely necessary to move the trundle section back to the position of itsy releaseand to raise the cou- At night it may beV plerfba'r" 26 onto the tongues of brackets 56k ferentform of the bed, ,one point of difference l beingzthat-here the equalizer bars are permanently securedy to and under the trundlebed. For ,Y

convenience, the same or similar'referencecharacters lare used for some of' .the corresponding parts. 5 The-upholstery'is numbered 4, asin Figure 1. VThe main mattress Sissupported on'th main spring fabric 8 which is carried bythe main frame I0. The trundle frame |2Y carries spring fabric I4 and is mounted on rollers I8. The remainder of the structure however has numerous variations and therefore new reference characters are used, these being in the hundreds.

Rigidly secured to the front legs of the main bed frame, are brackets |22 which may be welded or riveted to the legs. The brackets |22 are provided with outstanding headed pins |24. Suspended between the pins 24 is a movable side bar or coupler bar |26 provided with slots |28 for fitting over the pins |24. 'Ihe dimensions of the pin |24 are such that the side bar |26 will not bind thereon. Side bar |26 is provided with an elongated slot |30 in one end thereof. The trundle frame I2 includes a rear side bar |32 which is provided near one end with a slot |34 similar to the elongated slot |30. Secured between the side bar |26 and the side bar |32 are two equalizer or guide bars |35 and |38 pivoted to each other at a central point |40. The guide bar |35 is pivoted at one end to a pin |42 which slides in the slot |34 and at the other y end to a pin |44 which is mounted in a suitable hole in the removable side bar |26. The other equalizer bar |38 -is pivoted at one end to a pin |46 slidably mounted in the slot |30, and at the other end to a pin |48 mounted in a Ysuitable hole in the side bar |32. As the trundle bed frame is slid in and out, the equalizer bars |36 and |38 insure equal movement of the two ends of the trundle bed and true running of the trundle bed as a whole. It follows that due to the use of these equalizer bars |36 and |38 it is impossible for the trundle bed frame I2 to rub against the legs 20 of the -main frame I0.

In order to permit the complete collapse of the equalizer bars |36 and |38, the bar |38 is provided with a stirrup portion |50 which ts around the other bar |36.

When it is desired to separate the trundle bed frame from the main bed frame, it is Vmerely necessary to raise the removable side bar |26 l from the pins |22 at both ends, by which operation the two frames become entirely disconnected so that one may be withdrawn from the other. To prevent interference between the side bar |26 and the legs |20, the latter maybe cut out, .as at |52. bar |26 to the main frame I0 may be varied in numerous ways. The bracket |22 may obviously be placed farther forward if desired, to make the pins more conveniently located. According to a simplied construction, the pins |24 may be located on the front of the legs |20', as indicated'in Figure 12. Although the side bar is an angle iron, its upper facemay be cut away as at |54, in order to permit the complete extension of the beds when the side bar is attached to the main frame.

To make the combination bed more easily moved, there may be provided brackets |56 which preferably have upturned ends |58. These brackets are located on the Vmain frame I0, as indicated best in Figures 10 and 11, and are located such that when the main frame I0 is lifted up the rear frame member |60 of thetrundle frame I2 will be securely held by therbrackets '|56 both against relative downward movement skilled in the art.

The manner of Y attachment of the side trundle frame I2 may be supported by special brackets, or'if not, it will besuiciently supported by the sidebar |26. Y 1 e Although no receptacle for bedding has been shown, such a receptacle could be provided in any manner desired, preferably by providing a box under the trundle frame, as in the structure of Figures 1 to 8.

It is to be understood that many otherV embodiments of this invention, including some in improved form, will be apparent, and in the course vof time more will be devised by those l'It is not desired that this invention be limited to the details described, for 1 its scope includes all such forms or'improvements as come within the spirit of the following claims, construed as broadly as the prior art will permit.

What is claimed is: v

1. A bed comprising a main section and a trundle section, a coupler bar normally secured rigidly to the trundle section but detachable therefrom, equalizer bars connecting said coupler bar and said main section and maintaining the same parallel andrrelatively centered transversely; said sections Vbeing separable by rolling apart when said trundle section is detached fromv said coupler'bar; and end bars on said main Vsec-V tion positioned to sup-port saidV coupler bar.

2. A bed comprising a main section and a trundle section, a coupler bar normally secured rigidly to the trundle section but detachable therefrom, equalizer bars'connecting said coupler bar and said main section andv maintaining the same parallel and relatively centered transversely; said sections being separable but rolling apart when said trundle section is detached from said coupler bar; and end bars on'said main section positioned to support said coupler bar; said end bars having a depressed portion for permitting said coupler bar to drop loose from said trundle section when desired.

3. A bed comprising two relatively telescopable sections both normally supported on Vthe floor, and interengageable members on said. two sections positioned to remain out of contact as long as both of said sections are resting on the floor, but so positioned when the sections are telescoped as to engage one another if the upper of said sections is lifted, and to support the lower ofsaid sections from the upper of. said secr coupler bar and said main section and maintain- Y ing the same parallel and relatively centeredV transversely, said sections being separable by roll` ing apart without movement of said main section when said trundle section is detached from said coupler bar,and means on the main sectionAV adapted to support the coupler bar directly at each, end thereof in a'positionconvenient for coupling when disconnected lfrom saidtrundle section. e
